C<Carp::Crock> errors and returns them in the C<$error> string.

One very useful application of the C<load_package> subroutine is in test scripts. 
If a package does load, it is very helpful that the program does
not die and reports the reason the package did not load. 
This information is readily available when loaded at a local site.
However, it the load occurs at a remote site and the load crashes
Perl, the remote tester usually will not have this information
readily available. 

Other applications include using backup alternative software
if a package does not load. For example if the package
'Compress::Zlib' did not load, an attempt may be made
to use the gzip system command. 

=head1 BUGS

The C<load_package> cannot load program modules whose
name contain the '-' characters. 
The 'eval' function used to trap the die errors
believes it means subtraction.
